    I bought one of the first 50 and then one of the second batch to put on a machine gun and my kac sr15 years ago.

    I liked them a lot but ultimately doubt it was worth the $

    A few more from the collection.


    JP Enterprises brake. Loud but very effective on a .300 Win Mag. Friend count: 0.
    03A9F600-4383-4F01-843C-7A8661E415E2.jpeg

    Seekins Precision ATC brake. Keeps this 6.5 Creedmoor on target after the shot. Fairly effective and not nearly as loud as side blasting brakes (baffles are angled back). Friend count: the guy 2 lanes over.
    4D6CB71C-A291-4BC7-B696-923A3A47DF84.jpeg

    RRA comp. A hybrid that’s all you need on 5.56 and somewhat reasonable on noise. Make it 3 stalls down on noise with less concussion than most.
    2435203F-1BA9-484E-8F61-1B0AE8343CE2.jpeg

    Brockman brake. Radial that can be closed and, by claim and my chronograph, does not change velocity. Noise is reasonable as is effectiveness.

    F-1 compensating brake in TiCN. Loud. Effective. My wife says “pretty”.

    IMO, These are the only muzzle devices that should be used on a firearm. All the other types make too much damn noise.

    It is a muzzle brake, not muzzle break.

    I don't know if it is the best, but I am happy with the VG6 Gamma 762 on my 20 inch Aero Precision AR10. The good ol A2 flash suppressor does what I need it to on 5.56.

    I put a PA "Hypertap" on my 3gun carbine earlier this year and wow!

    it's loud and expensive, but when combined with the AGB, low mas bolt carrier and lightweight buffer/spring, it works extremely well:

    My other muzzle devices are griffin "Flash Comps" where I'm looking for a combination of 'both brake and flash hider".

    there are some very good reviews available on line to help guys get what they want to achieve. Here's just one compilation:

    I refuse to spend over $50 for a muzzle attachment. I ONLY use flashhiders, & the best performing 3P is under $50. For those who like comps/brakes...I mean, I don’t understand them on low recoil calibers, but if it’s your deal...cool. For me, the blast/noise is a deal breaker.

    Expensive muzzle attachments do not buy performance. Honestly, these super expensive units are all flash. A SUB $50 Brake does exactly what the more expensive ones do.

    I just went to a thread protector on one of my ARs. I also stuck a CMMG 22RF conversion unit in it for a kid to shoot. My son-in-law has an AR with just a thread protector and it's no fun to be off to the side of when it's fired. When this gun turns back into a 223 it will have it's bloop tube back in place and send some of the noise down range.

    I recently bought a Witt Machine SME, it's a really good concept in theory, but the company's execution really sucked and customer service was worse. I want to be able to recommend it so badly, but I can't due to the terrible QA and customer service. Witt Machine sent the wrong color and the cerakote was terrible -- it looked like one thin coat of rattle can paint and the company refused to replace it, saying that the "cerakoter was new and is still learning". For the price of $175, I'd expect it to be flawless, or at least to have a decent CS backing when it's bad.

    It does knock down a lot of sound, but I feel like after getting it that it's a suppressor that is flying under the radar since it's a three chamber brake with a shroud with a few thousandths of clearance...basically making three sealed chambers. They don't have an ATF determination letter, so these may go the way of the Q Honey Badger at some point.

    Kaw Valley linear comps are the best I've found in general.

    Wait, so this doesn't count as a "suppressor" subject to NFA?

    Most of the flash suppressors in the AR world differ primarily in appearance and/or cost, in my experience. What matters the most is that it is compatible with whatever can you will be using, if you will be using one. The standard A2 and the slightly different SOPMOD version which interface with the GEMTEC HALO and KAC QD suppressors, respectively, are what I have the most experience with- either are more than adequate for any military use I have ever experienced, either suppressed or "ran loud".
    When I was an instructor at Ft Bragg, I had the opportunity to fire the AK74, and I noted the efficiency of the brake (but loud). I ended up putting a similar design from Bushmaster on the AR (about $25 as I recall) I dedicated for 3 gun competition. It definitely made a difference in stages that required maximum speed, and it also aggravated the heck out of the RSO's with the pro-timer. I didn't feel a thing, and I told them they may want to position themselves behind me, but not all of them listened.
    I am awaiting delivery of a PSA flash can to put on my AR10 carbine that I occasionally use for deer hunting. I've never used one, so I am curious how it will be.

    A long flash hider that’s pinned and welded to a 10.5” barrel. This one is on my junkyard build and fun to shoot.

    I only own one lonesome AR. I took one of those and sawed it off just behind the slots, stuck in in the lathe and trued up the end and that is what I use. I call it a bloop tube as it does nothing except direct the sound out in front of you. It really makes a difference in the noise level under the tin roof over the firing line at my range when I am playing with load development or just shooting paper or steel.

    It does not make the gun quitter. It just directs the sound forward so, not a NFA item.


    You basically made a skinny flash can.
    Flash cans are not that expensive. You can find the as low as $20 to $30.
    Here’s a few.

    That has been my experience also. The A2 works fine for me and has for 30+ years. Out of all the different AK rifles I shot on full auto, the AK74 was definitely the most controllable.

    I do have one flash can but it doesn't really do much since it is on a 4.5" AR22. The only reason for using it was to clear the 3 1/2" hand guard.

    Linear comps are excellent at directing sound away from the shooter but last weekend proved they don’t attenuate noise for others. My date was shooting my 7.5” (5.56) on the last lane indoors and the entire line stepped back to see what was making the ruckus. ‘Course they did the same when we broke out the PMR30.


    I didn’t notice till afterward the rather odd firing position she took, and not for nothing, her contacts are adjusted 1-near, 1-far. Right hand, left shoulder.

    Krink brakes on everything. These little guys are amazing. I think I have 7 or 8 of them now.

    Thanks for the link, gunny but what I have, call it what you wish, works to my satisfaction.

    No kidding, just pay a bit extra and purchase a suppressor. Crazy money for a muzzle device.

    To the guys that have the hollow can blast forwarders, if yours doesn't have the cone shaped baffle that threads into the end like the krink brake 3 posts above, you are missing about 70% of the benefit. I have tried it myself shooting with and without the baffle many times on several different calibers from 9mm to 358 and there is no comparison.

    Well, I had hoped that Other Rifle types were included——oh well.

    My Hungarian (FEG) rifle with a 12” barrel has a nice flash on cloudy days.

    But.... Will they launch a 22mm rifle grenade?

    Allow a bayonet to be mounted....?

    Accept a Blank Firing Device....?

    Improve barrel harmonics....?

    And suppress flash....?

    ....Or just tame that mighty .223 recoil?

    I would have to respectfully disagree. There is, for me, a very distinct advantage to having a good muzzle device on your carbine. I was pretty much in the same camp as you not wanting to spend the $$$ for what I suspected would be a pretty negligible difference but decided I'd give one a try. The 1st iteration of the now sort of rare Griffin Armament FlashComp M4SD II, the one with tiny holes instead of large ports works as a comp and a flash hider and does a pretty good job at both.

    I wanted to know if I'd spent wisely so I waited a lil over 10 days after I got it to install it and waited for my buddy to come over with his identical carbine, only difference being his still had the A2 birdcage and a Holosun red dot instead of a Primary Arms red dot, and I was immediately impressed with the device's ability to mitigate muzzle whip. It did exactly what the reviewers said it did, the muzzle didn't have nearly as much bounce and climb during rapid and semi rapid shot strings and it stayed on target better and with less effort.

    To make sure I wasn't like one of those lil kids with brand new Jordan basketball shoes thinking he can run faster and jump higher, I had my buddy test it out and after comparing targets I had conclusive proof that it improved both mine and his shooting specifically in terms of 2-3-4-5 rd bursts of fire. I really like flash comps now, especially the M4SDII, since my experience with muzzle device's is pretty limited.

    I'm also a fan of the BCM Mod 0 FlashComp and the ol' standard A2 flash hider is great considering they can be had for $7 and come with pretty much every off the rack AR15.

    I've been wanting to put a JP 3 prong flash hider on my bedside pistol but they are discontinued for the time being and I haven't seen any, but from what I'm told they offer a 98% reduction in flash and which is about as good as it gets and with the right ammo, Black Hills specifically, I'm told there is basically no flash and for a HD AR I think that's important. In the absence of the JP I've been considering the Surefire flash hider which is supposed to be one of the best also.......

    All joking aside a good muzzle brake on a 223 does make a big difference but it’s not about recoil, I doubt there is any significant percentage of people that actually think an AR15 in 223 needs less recoil. It’s the sight disruption due to muzzle rise. Shooting a 223 from the bench even in a 10 lb gun it’s pretty difficult to see your hits in the scope because of the rifle jumping in the rest. With a good muzzle brake there is so little sight disruption you can see your bullet hit the target in the scope, even from a bipod. I would have one on every rifle I own if it weren’t for the problem of muzzle blast and hearing damage.

    I prefer the Smith Vortex & YHM flash hiders for my rifles. I tried a Strike Venom. While it looked awesome, it hid ZERO flash

    Please remember that this topic is not to debate which is best, or if muzzle devices are needed.
    This topic is to let members see what is out on the market and for those of us that have personal experience, to share with others.
    Back when I built my 458 SOCOM, the recoil was a bit much for the nerve damage in my shoulders. Having a good bit of experience with muzzle devices, I pretty much knew what I was looking for. But when it came to muzzle devices for low muzzle pressure cartridges like the 458 SOCOM, there wasn’t much on the market that worked very good.
    I went to see my friend Zack over at Aklys Defense. Zack is a great guy and a great design engineer. We talked about what would be needed to make a good muzzle brake. Zack told me to give him a little time and he would design and build a muzzle brake for me. This is what he came up with.
    This is the prototype he built and we used mu rifle the test it. I provided the ammo.
    ED13382D-2188-4F44-8BB5-EC174E7FEA80.jpeg

    The muzzle device worked great to reduce the recoil, and it also reduced muzzle climb. Joe, the owner of Aklys liked it so much that we sat and talked about what they would name the brake if they decide to market them. The name Megalodon was at the top of the list.
    A few months later I was surprised to see it listed on their wed site and the name they gave it. My last name is Bihm.
